[PATCH v2 28/34] drm/xe/vf: Add debug prints for GuC replaying state during VF recovery

[Matthew Brost <matthew.brost@intel.com>]

Helpful to manually verify the GuC state machine can correctly replay
the state during a VF post-migration recovery. All replay paths have
been manually verified as triggered and working during testing.
